Abstract: L'invention concerne un instrument chirurgical libérant plusieurs atomes de gaz inerte haute énergie, du type argon, dans un flux qui permet de découper, cautériser ou évaporer des tissus. L'appareil comprend une source de gaz inerte, une cellule à plasma communiquant avec ladite source pour appliquer une énergie aux atomes de gaz inerte, définie en partie par une électrode positive et une électrode négative, et au moins une source de courant continu reliée entre les électrodes. La source de courant fournit d'abord une tension d'ionisation entre les électrodes pour établir un plasma dans la cellule à plasma à partir du gaz inerte, puis une courbe de tension impulsionnelle entretenant le plasma à un niveau d'énergie prédéterminé. Cette courbe peut comprendre un schéma répété de tension de crête correspondant à une première durée suivie d'une tension minimum correspondant à une seconde durée. La tension minimum peut être supérieure ou égale à zéro. La courbe peut également être appliquée par le biais d'une bobine d'induction de manière à engendrer une courbe de courant du type à configuration en dent de requin au niveau de la cellule à plasma. L'instrument peut encore comprendre une pièce à main ayant un corps tubulaire, qui renferme la cellule, et une extrémité dotée d'un canal en communication avec la cellule à plasma, pour l'émission des atomes de gaz inerte depuis cette extrémité. L'invention concerne également un procédé relatif à l'exécution d'une procédure chirurgicale de découpe, de cautérisation ou d'évaporation de tissu corporel, ou une combinaison de ces opérations, au moyen de l'instrument décrit.

Title: Method and apparatus for measuring and controlling the exposed length of a tissue cutting device in an endoscopic catheter
Inventor: GRIEGO JOHN
IPC: A61B17/34
Filed: 2002-09-27
Abstract: According to the present state of the art, endoscopic cannulation of the common bile duct and papillotomy and/or sphincterotomy of the Papilla of Vater and/or the Sphincter of Oddi is accomplished by advancing a sphincterotome (or papillotome or cannulotome) into an endoscope/duodenoscope sothat the distal tip of the sphincterotome exits the endoscope adjacent the sphincter muscles at the Papilla of Vater. The endoscope mechanisms are then manipulated to orient the distal tip of the sphincterotome to the desired position for proper cannulation of the duct. Accurate and consistent control of the length of the exposed blade is made difficult due to a number of factors. These factors include: 1) differences in the inside diameters of the outer tube and the needle knife wire, 2) the orientation of the needle knife wire within the outer tube, 3)the mismatch of tolerance of the needle knife wire and the inside diameter of the extrusion, 4)anatomy, and 5)endoscope manipulation. A  sphincterotome incorporating the present invention will provide the user with an indication of the exposed blade length and will allow the physician to control the length of the exposed blade. According to one embodiment of the present invention, various visual indications are presented to the user as the needle knife is advanced from its outer sheath. These visual indications, combined with a mechanical method to hold the knife in position during catheter placement allows the use to perform precise incisions. Presently available products that may be modified according to the present invention include, but are not limited to, Boston Scientific Sphincterotomes and Needle Knives.

Title: Dispensing syringe
Inventor: PIERSON PAUL R
IPC: A61C5/04
Filed: 2002-01-11
Abstract: A dispensing syringe (10) has a barrel (20) keyed (31, 32) to a gripping assembly (40) having complementary keyed surfaces (42). A nut having dual threads (61, 62) of differing diameters is threaded to one end of the barrel (20) and receives a matingly threaded (71) plunger (70). Turning the plunger (70) causes it to advance within the barrel (20) due to the interaction of the mating threads (62, 71). The gripping assembly (40) is provided with winged projections (50) that facilitate handling and manipulation of the syringe (10). The complementary keyed surfaces (31,32 and 42) physically interact so as to prevent the gripping assembly (40) from turning or twisting about the barrel (20) during use.

Abstract: In general, the invention is directed to techniques for creating and controlling a magnetic field for use with electronic article surveillance (EAS) markers. In particular, the techniques make use of current switching devices to generate a signal having one or more current pulses for creating the magnetic field. An electronic article surveillance (EAS) system includes a coil to create a magnetic field for changing a status of an EAS marker and a drive unit to output a signal having one or more current pulses for energizing the coil. A programmable processor within the EAS system controls the drive unit to generate the output signal according to a desired profile. By selectively activating and deactivating current switching devices within the drive unit, the processor can direct the drive unit to generate the output signal according to a desired profile having a number of current pulses of different amplitudes and direction.

Abstract: The method for hair removal applies an electrolytic procedure, followed sequentially by a thermolytic procedure. The electrolytic method involves preparing the area to be treated by allowing silver/silver chloride gel to remain on the area for a period long enough to allow the electrolyte gel to diffuse through the skin, then applying a cotton swab to a galvanic probe and swabbing circles of the electrolyte gel about the treatment area while applying galvanic current for two passes about the area.      Then the hair is grasped by tweezers before removing the electrolyte gel from the area, and an RF current is applied through the tweezers for twenty to twenty-five seconds while gently pulling the hair.

Abstract: A method for cooking low or zero fat potato chips, for hot serving and immediate consumption, which uses zero or minimal amounts of cooking oil or fat. These chips may be known as "fries" in some regions. The cooking takes place in oxygen free gas instead of cooking oil.  Higher temperatures than with oil and elevated pressure are used to avoid slower heating and cooking that might otherwise follow without oil. Particular care is taken to monitor moisture content and achieve an external crispy layer which does not become soggy before the chips can be reasonably consumed, to compensate for the absence of sealing oil which slows the sogging process. A searing phase may optionally be added to thicken the crisp outer layer and further defer the onset of sogginess, to add desirable brown or bronze or golden colour, to make the low fat chips more competitive with conventional oil cooked chips. Pizzas, sea food, and other foods can be cooked, to advantage, in oxygen free gases, at higher temperatures, yielding accelerated cooking times, and without extraneous and possibly not most healthy auxiliary ingredients added for convenience of the cooking process. Coffee, and other food substances needing to be stored after opening, can be kept fresher in storage for a longer time, by storing them in compressed oxygen free gases, such pressure being sufficient to prevent the backflow of atmospheric air, bearing oxygen and moisture.
